Upgrading the SRAM PG-1130 [paid link] cassette is a common consideration for cyclists aiming to enhance drivetrain efficiency, climb performance, or improve weight distribution. Whether you’re replacing worn components or exploring gearing changes for specific terrain, it’s critical to understand the upgrade pathways, what components are compatible, and how to execute changes without compromising performance.
This guide covers essential details about upgrading the SRAM PG-1130 [paid link] cassette, ensuring cyclists make informed, technically sound decisions that align with their drivetrain system.
Understanding the SRAM PG-1130 Cassette Design
The PG-1130 [paid link] is a value-oriented 11-speed cassette in SRAM’s Rival-level [paid link] drivetrain ecosystem. Built with durable steel sprockets and designed to be compatible with standard 11-speed Shimano/SRAM freehub bodies, the PG-1130 features wide-range gearing options like 11-28T, 11-32T, and 11-36T.
It uses SRAM’s PowerGlide II technology for smooth gear transitions and is widely favored for its blend of cost-efficiency and reliable shifting. However, it lacks the lightweight materials or intricate machining of higher-end cassettes, prompting many riders to consider upgrades.
Why Upgrade the SRAM PG-1130 Cassette?
There are several compelling reasons to consider upgrading:
- Weight Reduction: The PG-1130 uses stamped steel sprockets, making it heavier than higher-end options like the XG-1150 [paid link] or XG-1175.
- Improved Shifting Precision: Premium SRAM cassettes offer more advanced ramping profiles for crisper shifts.
- Gearing Optimization: Riders may seek tighter or broader gear ranges for specific riding conditions.
- Aesthetics and Material Durability: Upgraded cassettes often include anodized aluminum or machined steel, improving both looks and wear resistance.
Compatible Upgrade Paths for SRAM PG-1130
Upgrading from the PG-1130 involves staying within the 11-speed family or moving to a 12-speed system with other drivetrain component changes. Here’s what you need to know:
Upgrading to a Lighter 11-Speed SRAM Cassette
- XG-1150 [paid link]: Offers improved durability and weight savings; uses SRAM XD [paid link] driver.
- XG-1175: Features a machined steel design for lighter weight and improved shift performance; also requires an XD [paid link] driver.
Compatibility Note: These upgrades require a switch from a standard freehub body to an XD [paid link] driver body. Ensure your rear hub supports this change, or you’ll need to replace it.
Shifting to a 12-Speed System
- Requires full drivetrain upgrade: shifters, derailleur, chain, chainring, and cassette.
- Must use SRAM’s Eagle or AXS-compatible ecosystem.
- Provides broader gear range with 10-50T or 10-52T options.
This is a high-cost transition but is often pursued for modern gravel, XC, and all-road setups where gear versatility is critical.
What to Consider Before Upgrading
1. Freehub Body Compatibility
The PG-1130 is designed for HG (HyperGlide) freehubs. Most higher-end SRAM cassettes (e.g., XG series) use the XD driver body. Confirm your current hub and determine if a swap is feasible.
2. Rear Derailleur Capacity
Ensure your rear derailleur can accommodate the largest cog of the upgraded cassette. For example, a PG-1130 with 11-36T might already be at the upper limit for a medium cage derailleur. An upgrade to 11-42T would likely require a long cage version or even a new derailleur.
3. Chain Compatibility
A new cassette with different tooth profiles may require a new chain. Always install a fresh chain with a new cassette to prevent premature wear and shifting issues.
4. Gear Ratio Planning
Understand your gearing goals. Are you climbing steep terrain more often? A broader range like 11-42T may be ideal. Prefer tighter spacing for road racing? Consider 11-28T or 11-32T cassettes for more consistent cadence control.
Best Practices When Upgrading from PG-1130
- Measure Chainline and Drivetrain Wear: Before any upgrade, use a chain checker and inspect the chainring and derailleur pulleys.
- Replace Chain Simultaneously: Never run a worn chain on a new cassette.
- Upgrade Derailleur Only If Necessary: Don’t replace your derailleur unless the cog size or tooth jump demands it.
- Use SRAM-Specific Chains for SRAM Cassettes: This ensures ramp alignment and optimal shift performance.
- Avoid Mixing SRAM 11-Speed Cassettes with Shimano 11-Speed MTB Components: While some combinations may physically fit, they often result in poor shifting due to incompatible cable pull ratios or ramp designs.
When Not to Upgrade the PG-1130 Cassette
An upgrade might not yield significant gains in certain scenarios:
- Minimal Weight Savings for Cost: If your main goal is weight reduction, moving from a PG-1130 to an XG-1150 [paid link] may not justify the cost-to-benefit ratio unless you’re optimizing for competition.
- Commuter or Training Use: For everyday riding, the PG-1130’s durability and affordability make it a sensible long-term choice.
- Compatibility Limitations: If your current hub doesn’t support an XD driver and you’re not ready to overhaul your wheel or drivetrain, staying with the PG-1130 is a better short-term solution.
Conclusion
Upgrading your SRAM PG-1130 cassette can significantly enhance ride quality, reduce weight, and fine-tune gearing performance—if done strategically. Evaluate your current hub compatibility, derailleur capacity, and performance needs before committing to a higher-end model. Whether you aim for a subtle improvement or a full drivetrain overhaul, understanding your upgrade path ensures smooth shifting and a better riding experience.
Frequently Asked Questions (FAQs)
1. Can I upgrade from PG-1130 to XG-1150 without changing my hub?
No. The XG-1150 cassette uses an XD driver, which is not compatible with standard HG freehub bodies.
2. What chain should I use with an upgraded SRAM cassette?
Use a SRAM 11-speed chain for 11-speed cassettes or a 12-speed chain for Eagle setups. Match the chain to the cassette series for best results.
3. Is the PG-1130 compatible with Shimano derailleurs?
Technically yes, but shifting quality may suffer due to cable pull ratio and ramp differences. Mixing brands is not recommended.
4. Will a PG-1130 cassette work with a long cage derailleur?
Yes, and it’s often required if you’re running wider ranges like 11-36T or considering an upgrade to 11-42T.
5. How much weight can I save by upgrading from PG-1130 to XG-1175?
Expect around 100-150 grams of weight savings, depending on the model and range selected.
6. Can I use a 12-speed chain on my PG-1130 cassette?
No. The chain width and tooth profile are not compatible. Always use an 11-speed chain with 11-speed cassettes.
